hey, im new on the forum, but have been into RC nitro trucks for about 2 years, im 16 so, i don't know much.

Im running a TRX 2.5 in a custom chassis(aluminum) with a mix of blue anodized aluminium and plastic, as well as a custom exhaust..

i want to change the Exhaust so it's sounds deeper (like aftermarket exhaust on a car). Right now it's your typical high pitched sqeaul. is it even possible to make an exhaust like this? How couldm i go about doing this?

Thank you,
Xavier

its a two stroke you cant really get that deep rumble like out of a 4 poke but try some exhausts i guess but you are probably going to live with the sound

Pipes made from thicker aluminum will give a slightly lower pitched sound, but it will still have a very high pitch with that Small block you're mounting it to..

would it be possible to make a custom one, with a 1/2 inch from the engine, then to a 1 inch body wiht baffleing(and hole for backpressure line) and then to a 3/4(or slightly smaller) output ? would that help

Is this a stock TRX pipe? If it is get the single chamber TRX pipe and if you don't race bore out the stinger.

no, i bought used with a cracked(didn't know till i washed with acetone) alum. exhaust, with that it's 1/4inch to 1inch(bore) to 1/4inch output... it's a shitty thing, but i got it all for like 100$ a year and a half ago..

jjshbetz11

if im following you the output is the stinger. I take the quarter inch is outer diameter? Sounds like a big block pipe.

what do you mena by stinger?? is that the stock exhaust?

jjshbetz11

Does it have a name on the pipe?

jjshbetz11

The stinger is where the actual exhaust would come out at. You got a header, then the "pipe" and the stinger comes off of the pipe.

no, what's mounted on it now is a custom alum. one, the stock black one came with it if i wanted to put it back on.
i'd post pictures, but the site has a min. # of posts needed -.-

Custom? Would take a hella CNC machine for that.

blackjack233

not CNC, welded alum. it's weird i know, the sound wails like and SoB..

I would personally put the OG pipe back on it. Alot of science in tuned pipes and for one to just make one could really hurt performance.

blackjack233

so the OG, is the stock one?
